Forty years since Masterton's death on the Globe on Hockey Blog: "Masterton, 29 at the time, was checked by Larry Cahan and Ron Harris of the Oakland Seals, and hit his head on the ice after falling backwards. The game took place Jan. 13, 1968, in Bloomington, Minnesota, and Masterton died in hospital two days later due to a brain injury."

"His death led to the lobbying of more widespread use of helmets, and a mandatory helmet rule was passed in the summer of 1979." Anyone playing ice hockey should pause for a moment and remember Bill Masterton. His unfortunate death began a series of rule changes and other protective measures that have made our sport much safer.
